Really makes me feel immersed in the Japanese language. This is a common problem with Duolingo- no matter what language you study, the material just feels American 
And before you ask, no, I did not pay for the subscription, they randomly gave me three free days of Plus, or Super, or whatever it is. Imagine paying for Duolingo 
American? It's clearly a Liberian flag https://www.flagdetective.com/liberia-flag.htm
I never realised Liberia was just America but in Corporate Memphis
Liberia is an absolutely wild country, America's only formal colony (as opposed to its many, many de facto colonies in the 19th and 20th century) founded by Americans who thought black slaves should be sent back to Africa, and ruled by members of the free African American Bourgoisie. Of course no one told the people already living there, and the consequences of having a massive extractive divide between settler colonists and African cultures in the interior has had no negative effects whatsoever.
Brits drawing straight lines on maps wish they could create a country half as fucked up by design as Liberia.
